Patent EP-0548863-A1 (EP)
Inventor: HEZEL RUDOLF DR
IPC: H01L31/0216
Filed: 1992-12-19
Abstract: A solar cell (10) having at least one semiconductor substrate surface (12) is proposed, which has projections (24, 26, 28) on which electrically conductive contacts (20) are constructed for dissipating charge carriers and which is covered by a passivation material (16), at least between the electrically conductive contacts. In order to be able to produce solar cells of high efficiency using simple technology, after construction of the projections, the semiconductor substrate surface is covered over the entire area, or largely over the entire area, with the passivation material. Existing passivation material and possibly semiconductor material is then removed from the projections. The material forming the electrically conductive contacts is subsequently arranged on the regions of the projections thus exposed. <IMAGE>

Title: Device for processing the surfaces of pipes.
Inventor: BAUR FRITZ
IPC: F16L55/168
Filed: 1992-01-23
Abstract: The invention concerns a device for processing the surfaces of pipes, for instance for winding them with anti-corrosion tape, the device having a tool carrier, fitted with rollers, which can be placed against the pipe surface. The angle which the axes of rotation of the rollers make with the axis of the pipe can be adjusted to give the desired contact length. The tool carrier (2) is designed so that its rollers (3, 4) grip the pipe like a claw, at least one guide roller (10, 11) for a continuous drive belt (15) being mounted on the tool carrier (2) near the end of each claw arm, the drive belt passing round the side of the pipe (1) remote from the tool carrier (2). One of the rollers (10) is designed as a drive roller and is linked to a drive motor (12). The other roller (11) is designed as a brake roller and is linked to a preferably adjustable brake (14). The drive roller (10) and the brake roller (11) are mounted so that they can be staggered with respect to each other relative to the diametrical plane of the pipe. This enables large pipes to be wound using a small tool carrier, since it is merely necessary to fit a suitably long drive belt.

Abstract: Procédé permettant de récupérer dans une solution du nickel existant sous forme soluble et dans des concentrations relativement faibles, plus spécifiquement dans des concentrations s'élevant jusqu'à 2 % en poids. Dans ce procédé: (a) on précipite le nickel de la solution (de préférence sous forme d'un hydroxyde ou d'un sulfure); (b) on ajoute un support particulaire inerte et un floculant dans la solution pour former des flocons constitués du précipité de nickel, du support particulaire inerte, et du floculant; (c) on sépare les flocons de la solution (de préférence par décantation gravitationnelle ou séparation magnétique); et (d) on sépare le précipité de nickel des flocons (de préférence en agitant les flocons). Ensuite le précipité de nickel et les flocons traversent de préférence un filtre pour enlever le nickel sous forme de gâteau de filtre. Le support inerte est de préférence du sable, de l'oxyde d'aluminium, de la magnétite, de l'hématite, de l'ilménite ou de la calcite. Le floculant est préférablement un floculant cationique, non ionique ou anionique.

Abstract: Appareil et procédé d'annulation d'écho dans des systèmes de messageries vocales et de réponses vocales, afin d'améliorer la reconnaissance de signaux DTMF et vocaux reçus, comprenant un annuleur d'écho de logiciel efficace utilisant des techniques de filtration numérique adaptative. Le système de messagerie vocale (1, figure 1) comprend des modules d'interface de lignes téléphoniques analogiques (24) qui fournissent des données vocales numérisée à une puce d'un processeur de signaux numériques (DSP). Une ligne de données de transmissions (204, figure 3) et une ligne de donnée de réception (202) sont chacune couplées à un module d'annulation (208) avec un filtre d'annulation et un module d'adaptation/fenètre (220) avec un filtre numérique adaptatif. Le filtre d'annulation provoque l'annulation d'écho sur la ligne de données de transmission; le module d'adaptation/fenêtre contrôle les données de transmissions temponnées en temps non réel, sans provoquer directement l'annulation, et transfert de manière sélective une fenêtredddjacente de coefficient de filtre au filtre d'annulation sous la commande d'une commande d'adaptation (230) couplée au module d'adaptation/fenêtre. La commande identifie une pluralité de séquences qui satisfont un critère de puissance et fait passer les séquences vers le filtre adaptatif, qui adapte des prises dans les segments des séquences pendant tous le temps réel DSP disponible en utilisant une caractéristique "de vol de cycle" pour tester si des cycles supplémentaires du processeur DSP sont disponibles pour l'annulation d'echo.

Abstract: In a multi-processing system (10), a cache controller is implemented to efficiently process collisions which occur when a predetermined address location in a data memory (26) is simultaneously accessed by two processors (20, 21). The cache controller is formed by both a cache control logic circuit (34) and a tag unit (36). In tag unit (36), a snoop tag cache (40) and a data tag cache (42) respectively indicate whether a snooped value or an accessed data value is stored in data memory (26). A status bit array (41) provides status information for both tag caches (40, 42). By configuring array (41) to store status information for both snoop and data tag caches (40, 42), status information is "forwarded" between tag caches (40, 42) when a collision occurs. Additionally, the cache controller modifies the timing of each of the accesses such that the status information may be "forwarded" more easily. The timing modification is also referred to as "resource pipelining."

Abstract: A stable aqueous detergent composition in liquid or gel form containing from 10 to 80% by weight of an active detergent mixture comprising primary alkyl sulphate in an amount of 15 to 75% by weight of the active detergent plus betaine and/or amine oxide in an amount of 10 to 40% by weight of the active detergent mixture. Primary alkyl sulphate having chains of 10 or 11 carbon atoms provides at least 25% by weight of the primary alkyl sulphate present. The betaine and/or amine oxide is at least two thirds of the amount by weight of any primary alkyl sulphate having carbon atom chains of 12 carbon atoms or longer. 
     The C₁₀ and/or C₁₁ alkyl sulphate is surprisingly effective as a detergent in such compositions despite higher water solubility than longer chain alkyl sulphate. It can enhance mildness compared to longer chain alkyl sulphate, and can replace or partially replace alkyl ether sulphate. Nonionic detergent may be included to enhance mildness further.

Abstract: A DC plasma jet method enables us to synthesize diamond at a high speed by spraying an activated carbon-containing gas as a plasma jet to a substrate. Despite the high speed deposition, the method cannot synthesize a wide uniform diamond owing to the ununiformity of the jet and the restriction of sizes of torches. Uniform deposition of diamond on a wide substrate is a purpose of this invention. 
     More than two anode-nozzles (2,3,4) and more than one plasma torch (1) are utililized. They are disposed with their center lines crossing at a point. An inert gas or hydrogen gas are supplied in the torches in order to excite inner arc plasma jets. Then the torches are applied a negative DC voltage. The anode-nozzles are applied a positive voltage and are supplied with an inert gas, hydrogen gas or both an inert gas and hydrogen gas. Outer transferable plasma jets are formed between the cathodes of torches as cathodes and the nozzles as anodes. The plasma arc jets are integrated into a unified plasma flame. The nozzles and the torches are moved or rotated in order to enlarge the plasma formation areas. A carbon-containing gas is supplied to confluences of the plasma jets from the cathode-torches and the anode-nozzles from gas supplying nozzles (5,6,7).
